My PH keeps wanting to climb, unless I add acid about once every week or two. Don't have an SWG (wish I did!), and it has rained alot, so can't figure out why. Anyway, in keeping my PH down, I think I have accidently done the "lowering the Alk" procedure, because we run our fountains and bubblers alot too. My Alk was raised up from 80 to 130 about a month ago (PB added baking soda), and it has been creeping down ever since. Now it's 70.

Should I leave PH alone until after I get my TA where I want it? I think I read that somewhere, but can't find it now. If I have a 22,000 gal, vinyl IG pool, how much baking soda should I add? Can I put it in the skimmer? Should I dissolve it first? How long after I add can I do an accurate test, and then add acid to bring PH down?
